GAS-MIXER.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed September 8, 1908. Serial No. 452,117.

To all whom "it may concern:

Be it known that I, CHARLES V. PoLLoox, a citizen of the United States,residing at Madison, in the county of Dane and State of Visconsin, haveinvented a certain new and useful Improvement in GasMixers, of which thefollowing is a specification.

My invention relates to a fluid mixer, particularly such as is to beused for mixing gas and air to produce a highly combustible mixer to beused for securing high tempera ture.

It' is illustrated in the accompanying drawing, wherein the figurerepresents a side elevation With parts broken away to show the internalstructure.

A is a cylindrical case having the top B, the bottom C and the verticalshaft D. On this shaft are mounted a series of fan-like structures withcurved wings, each successive fan having wings curved in the oppositedirection. The fans having wings rotating in one direction are indicatedby the letter E and those which rotate in the opposite direction by theletter F. Along the sides of the cylinder are the two verticaldeflectors G G, each provided with a series of short diagonally placed,funnel shaped discharge pipes J. The gas inlet K opens back of one ofthese deflectors, and the air inlet L back of the other.

M is a supplementary gas inlet having a long discharge pipe N within thecase.

0 is a supplementary air inlet having a long discharge pipe P within thecase.

R is an annular flange in the top of the case above the deflectors, andS is a discharge pipe at the upper portion of the case.

I wish my drawings to be taken as diagrammatic and also to have itunderstood that the various forms and constructions shown are offered assuggestive of the various ways in which the principle of my inventionmay be practiced. I do not wish to be limited to the precise form andarrangement and proportion of the parts shown for I know that theprinciple of the invention may be utilized in greatly varyingstructures.

The use and operation of my invention are as follows :-The gas isintroduced through the inlet pipe K and air through the inlet pipe L.The inclined pipes from their respective deflectors are stationed inopposition to their respective associated fans, the result being thatthe two series of fans are rotated in opposite directions, thusthoroughly stirring and mixing the two inleading gases. The mixedproduct is taken out of the discharge pipe S. The action is furtherfacilitated by the long inleading pipes N and P in the bottom of thecase, which are also arranged at their discharge ends so as to dischargeupwardly through the moving fans thus aiding the mixing process.

I claim:

1. A gas mixing device comprising a chamber, a plurality of gasinleading ducts, and intermediate them means for distributing and mixingsuch gases comprising a plurality of independent rotatable fan-likestructures, and means for directing the gas against their wings.

2. A gas mixing device comprising a chamber, a plurality of gasinleading ducts in the sides thereof, and intermediate them means fordistributing and mixing such gases comprising rotatable fan-likestructures, and means for directing the gas against their wings, saidfan-like structures adapted to successively rotate in oppositedirections.

3. A gas mixing device comprising a cylindrical chamber with a pluralityof inlea ding gas ducts in the sides thereof and discharging into thechamber, and a series of plates between the pipes in the chamber mountedso as to rotate, said plates arranged in tan-like form, the successivetans set to rotate in opposition directions.

4. A gas mixing device comprising a cylindrical chamber with a pluralityof inleading gas ducts discharging into the chamber, a series of platesbetween the pipes in the chamber mounted so as to rotate, said platesarranged in fan-like form, the successive fans set to rotate in oppositedirections, and deflector and distributing plates in front of the ducts.

5. A. gas mixing device comprising a cylindrical chamber with aplurality of inleading gas ducts discharging into the chamher, a seriesof plates between the pipes in the chamber mounted so as to rotate, saidplates arranged in fanlike form, the successive fans set to rotate inopposite directions,

and deflector and distributing plates in front posite directions, andsupplementary gas of the ducts, each consisting of a series of and airinleading devices which discharge tangentially arranged funnel shapedpipes. into the midst of such rotating fans.

6. A gas mixing device comprising a case, CHARLES V. POLLOCK. a seriesof rotatable fan-like structures, gas Vitnesses: r

and air inleading devices which discharge L. M. LEE,

against the fans so as to rotate them in op- H. ,H. RATOLIFF.
